Here is the script, Sorry for the late response:

It is good to know that someone has the same problem as me, because odoo support, did not solve this case.

Here is the main script: https://github.com/hydrosIII/odoo12-stock-correction

The script installss as a module and adds a cronjob in odoo. You can configure this job to run when you want. The script in my database takes all night to run, so we have another module that just checks quicky and depends on this script. This other one runs daily. The difference is that the first one checks all the database and all the dates. The second just checks the new bad recent entries.
